While the FX technology was lightyears ahead of the shoestring-budget FX seen in the original TOS 2 decades before, the FX technology seen in the first few seasons of TNG were kind of klunky when compared to even the remastered TOS FX.
Has anyone heard of a possible remastered edition of TNG?
Yes, there have been a few threads about this, and there's one huge hurdle which makes a remastered TNG extremely difficult. Unlike TOS, TNG was filmed and then edited on videotape. All the FX work was done on videotape, and the only completed, edited episodes are on videotape. There's no way to take that and do a high definition transfer.
Presumeably, the original film still exists, but there is no completed episode on film. Giving TNG the TOS-R treatment would be almost like taking the series back into production and re-editing every scene of episode with new special FX. This could be extremely expensive and impractical.
The producers basically f***ed themselves by trying to save money and edit the episodes on videotape.
